Common Name

2-[2-(acetyloxy)-5-hydroxy-3a,3b,6,9a-tetramethyl-4,7-dioxo-2h,3h,5h,5ah,6h,9bh,10h,11h,11ah-cyclopenta[a]phenanthren-1-ylidene]-6-methylhept-5-enoic acid

Description

2-[13-(Acetyloxy)-8-hydroxy-2,6,10,11-tetramethyl-5,9-dioxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]Heptadec-3-en-14-ylidene]-6-methylhept-5-enoic acid belongs to the class of organic compounds known as steroid esters. Steroid esters are compounds containing a steroid moiety which bears a carboxylic acid ester group. 2-[13-(Acetyloxy)-8-hydroxy-2,6,10,11-tetramethyl-5,9-dioxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]Heptadec-3-en-14-ylidene]-6-methylhept-5-enoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa).
